**R** é um ambiente computacional e uma linguagem de programação cuja popularidade vem crescendo rapidamente. O **R** é especialista em manipulação, análise e visualização gráfica de dados. Na atualidade é considerado o melhor ambiente computacional para essa finalidade e vem ganhando muitos seguidores no mundo. O ambiente está disponível para diferentes sistemas operacionais: Unix/Linux, Mac e Windows. Na internet você encontra grande quantidade de literatura para aprender **R,** eis algumas sugestões:

# Curso de Aprendizado de Máquina (AM) no Google

Author: Fabio FajardoJul 1

Tem interesse em aprender **Aprendizagem de Máquina** (ou aprendizagem automática ou também aprendizado de máquina ou machine learning? O Google disponibilizou um curso online de AM e AI (Artificial Intelligence). O curso é gratuito e está disponível em Machine Learning Crash Course e tem cerca de 15 horas de duração em videoaulas e traz mais de 40 aplicações práticas. O **Learn with Google AI** tem como objetivo fornecer acesso ao que há de mais avançado para ajudar desenvolvedores que tenham interesse em trabalhar com inteligência artificial. Apesar de não ter nenhum tipo de pré-requisito, a Google alerta que talvez seja melhor entender conceitos básicos de programação em Python antes de encarar o curso. Novos cursos sobre o tema deverão ser publicados dentro da plataforma em breve.
